Under these conditions, the enzyme exhibits full-site reactivity at its SHp, SHc and OHAc sites, but a concomitant 18-fold increase in Km of the coenzyme-A:OHAc transacylation reaction keeps the acyl-O-ester content of the acylated enzyme at less than 5% of the total.(ABSTRACT TRUNCATED AT 250 WORDS) This article has carcass characteristics been cited by other articles: (Search Google Scholar for Other Citing Articles) E.

| These genetic data support a revised model regarding the intra-molecular channeling of plump pics acetate and malonate within yeast fatty acid synthase. Quantitative acyl binding studies revealed a maximum of 2-3 mol rather than the expected 12 plump pics mol of malonate and of 6-7 mol rather than 24 mol of acetate bound/mol hexameric yeast FAS. Only 20-30% of the malonyl-enzyme and 35-50% of the acetyl enzyme represented performic-acid-labile thioester bonds. The binding characteristics of plump pics both substrates, exhibiting Hill coefficients distinctly lower than 1, as well as their non-linear Lineweaver-Burk and Scatchard plots, point to a marked negative cooperativity among the 12 yeast FAS subunits. The observed sub- stoichiometric substrate binding characteristics of the enzyme are ascribed to this effect. An a priori asymmetry of the complex appears unlikely since the coenzyme-A:FAS transacylation equilibrium may be shifted towards the fully acetylated enzyme in the presence of N- ethylmaleimide. |
